Janpoizz’s Crafting Mod allows you to craft many of the items only available by either finding them or in creative mode. This allows you to have more of these items readily available if you have the materials to craft them and to do so on your own terms. Items like saddles and horse armor are now easily crafted:

Rare blocks and ores are now craftable, including grass and moss stone blocks!

You can even craft creeper, zombie and skeleton heads.

And rare drops like fire charges and ender pearls are now easily made with this mod.

Important: Unfortunately this mod is no longer available!
